About Harmonic Drive Reducer
The Principle of Gear Transmission
Harmonic gear transmission was invented by the American inventor C.W.Musser in 1955. It is a new type of transmission that utilizes the elastic deformation of the flexible working member into the motion or power transmission. It breaks through the mechanical transmission using rigid members. The mechanism’s model uses a flexible member to achieve mechanical transmission, resulting in a range of special features that are difficult to achieve with other transmissions. The deformation process of the intermediate flexible member is basically a symmetrical harmonic. In addition to the former Soviet Union referred to this type of transmission as wave drive or flexible wheel drive, the United States, Britain, Germany, Japan and other countries are called “harmonic transmission.”
The Composition of the Gear Transmission
Circular Spline: it has 2 more teeth than the Flexspline and is generally mounted CZPT a housing.Flexspline: It is a non-rigid, thin cylindrical cup with external teeth on the open end of the cup. It fits over the Wave Generator and takes on its elliptical shape. The Flexspline is generally used as the output of the gear.Wave Generator: The Wave Generator is a thin, raced-ball bearing fitted CZPT an elliptical hub. This serves as a high-efficiency torque converter and is generally mounted CZPT the input or motor shaft.
Principle of Harmonic Gear Reductor
The principle of harmonic gear reduction is to use the relative motion of the Flexspline, Circular Spline and the wave generator, mainly the controllable elastic deformation of the flexspline to realize the motion and power transmission. The elliptical cam in the wave generator rotates in the flexible wheel to deform the flexspline. When the Flexspline teeth and the Circular Spline teeth enter and mesh with each other which are at the ends of the elliptical cam long axis of the wave generator, the Flexspline teeth at short axis ends are disengaged from the steel wheel teeth. For the teeth between the long axis and the short axis of the wave generator, the semi-engaged state which gradually enters the engagement along different sections of the 2 stages of the Flexspline and the Circular Spline is called a biting. It is in a state of gradual withdrawal from engagement, which is called disengaging. When the wave generator rotates continuously, the flexspline is constantly deformed, so that the teeth of 2 wheels are constantly changing their original working states during the 4 movements of meshing, biting, engaging and disengaging, generating a staggering tooth movement and realizing the motion transmission from the wave generator to the flexspline.

The Parts of a Gearbox
There are many parts of a Gearbox, and this article will help you understand its functions and components. Learn about its maintenance and proper care, and you’ll be on your way to repairing your car. The complexity of a Gearbox also makes it easy to make mistakes. Learn about its functions and components so that you’ll be able to make the best choices possible. Read on to learn more. Then, get your car ready for winter!
Components
Gearboxes are fully integrated mechanical components that consist of a series of gears. They also contain shafts, bearings, and a flange to mount a motor. The terms gearhead and gearbox are not often used interchangeably in the motion industry, but they are often synonymous. Gearheads are open gearing assemblies that are installed in a machine frame. Some newer designs, such as battery-powered mobile units, require tighter integration.
The power losses in a gearbox can be divided into no-load and load-dependent losses. The no-load losses originate in the gear pair and the bearings and are proportional to the ratio of shaft speed and torque. The latter is a function of the coefficient of friction and speed. The no-load losses are the most serious, since they represent the largest proportion of the total loss. This is because they increase with speed.
Temperature measurement is another important preventive maintenance practice. The heat generated by the gearbox can damage components. High-temperature oil degrades quickly at high temperatures, which is why the sump oil temperature should be monitored periodically. The maximum temperature for R&O mineral oils is 93degC. However, if the sump oil temperature is more than 200degF, it can cause seal damage, gear and bearing wear, and premature failure of the gearbox.
Regardless of its size, the gearbox is a crucial part of a car’s drivetrain. Whether the car is a sports car, a luxury car, or a farm tractor, the gearbox is an essential component of the vehicle. There are two main types of gearbox: standard and precision. Each has its own advantages and disadvantages. The most important consideration when selecting a gearbox is the torque output.
The main shaft and the clutch shaft are the two major components of a gearbox. The main shaft runs at engine speed and the countershaft may be at a lower speed. In addition to the main shaft, the clutch shaft has a bearing. The gear ratio determines the amount of torque that can be transferred between the countershaft and the main shaft. The drive shaft also has another name: the propeller shaft.
The gears, shafts, and hub/shaft connection are designed according to endurance design standards. Depending on the application, each component must be able to withstand the normal stresses that the system will experience. Oftentimes, the minimum speed range is ten to twenty m/s. However, this range can differ between different transmissions. Generally, the gears and shafts in a gearbox should have an endurance limit that is less than that limit.
The bearings in a gearbox are considered wear parts. While they should be replaced when they wear down, they can be kept in service much longer than their intended L10 life. Using predictive maintenance, manufacturers can determine when to replace the bearing before it damages the gears and other components. For a gearbox to function properly, it must have all the components listed above. And the clutch, which enables the transmission of torque, is considered the most important component.
Functions
A gearbox is a fully integrated mechanical component that consists of mating gears. It is enclosed in a housing that houses the shafts, bearings, and flange for motor mounting. The purpose of a gearbox is to increase torque and change the speed of an engine by connecting the two rotating shafts together. A gearbox is generally made up of multiple gears that are linked together using couplings, belts, chains, or hollow shaft connections. When power and torque are held constant, speed and torque are inversely proportional. The speed of a gearbox is determined by the ratio of the gears that are engaged to transmit power.
The gear ratios in a gearbox are the number of steps a motor can take to convert torque into horsepower. The amount of torque required at the wheels depends on the operating conditions. A vehicle needs more torque than its peak torque when it is moving from a standstill. Therefore, the first gear ratio is used to increase torque and move the vehicle forward. To move up a gradient, more torque is required. To maintain momentum, the intermediate gear ratio is used.
As metal-to-metal contact is a common cause of gearbox failure, it is essential to monitor the condition of these components closely. The main focus of the proactive series of tests is abnormal wear and contamination, while the preventative tests focus on oil condition and additive depletion. The AN and ferrous density tests are exceptions to this rule, but they are used more for detecting abnormal additive depletion. In addition, lubrication is critical to the efficiency of gearboxes.
Maintenance
Daily maintenance is a critical aspect of the life cycle of a gearbox. During maintenance, you must inspect all gearbox connection parts. Any loose or damaged connection part should be tightened immediately. Oil can be tested using an infrared thermometer and particle counters, spectrometric analysis, or ferrography. You should check for excessive wear and tear, cracks, and oil leaks. If any of these components fail, you should replace them as soon as possible.
Proper analysis of failure patterns is a necessary part of any preventative maintenance program. This analysis will help identify the root cause of gearbox failures, as well as plan for future preventative maintenance. By properly planning preventative maintenance, you can avoid the expense and inconvenience of repairing or replacing a gearbox prematurely. You can even outsource gearbox maintenance to a company whose experts are knowledgeable in this field. The results of the analysis will help you create a more effective preventative maintenance program.
It is important to check the condition of the gearbox oil periodically. The oil should be changed according to its temperature and the hours of operation. The temperature is a significant determinant of the frequency of oil changes. Higher temperatures require more frequent changes, and the level of protection from moisture and water reduces by 75%. At elevated temperatures, the oil’s molecular structure breaks down more quickly, inhibiting the formation of a protective film.
Fortunately, the gear industry has developed innovative technologies and services that can help plant operators reduce their downtime and ensure optimal performance from their industrial gears. Here are 10 steps to ensure that your gearbox continues to serve its purpose. When you are preparing for maintenance, always keep in mind the following tips:
Regular vibration analysis is a vital part of gearbox maintenance. Increased vibration signals impending problems. Visually inspect the internal gears for signs of spiraling and pitting. You can use engineers’ blue to check the contact pattern of gear teeth. If there is a misalignment, bearings or housings are worn and need replacement. Also make sure the breathers remain clean. In dirty applications, this is more difficult to do.
Proper lubrication is another key factor in the life of gearboxes. Proper lubrication prevents failure. The oil must be free of foreign materials and have the proper amount of flow. Proper lubricant selection depends on the type of gear, reduction ratio, and input power. In addition to oil level, the lubricant must be regulated for the size and shape of gears. If not, the lubricant should be changed.
Lack of proper lubrication reduces the strength of other gears. Improper maintenance reduces the life of the transmission. Whether the transmission is overloaded or undersized, excessive vibration can damage the gear. If it is not properly lubricated, it can be damaged beyond repair. Then, the need for replacement gears may arise. However, it is not a time to waste a lot of money and time on repairs.
